Revised March, 2012 3-17
Input Node ID and check the “Timer” checkbox to enable motion status display
NodeID item: API function's argument variable “NodeID”.
Timer Checkbox: Check to display the motion status. Uncheck to disable display.
3) Enter the values for acceleration/deceleration time and rotations per minute (RPM)
Figure 3.27
Tacc item API function's argument variable “Tacc”.
Tdec item: API function's argument variable “Tdec”.
RPM item: API function's argument variable “rpm”.
※Actual RPM is 10% of rpm variable.
4) Set Servo Motor Power ON/OFF(servo on/servo off)
Figure 3.28
Click on the “SVON” button to execute the following procedure:
rt = _DMC_01_ipo_set_svon(gDMCCardNo, NodeID, SlotID , ON_OFF);
// ON_OFF: 0 – Servo Power OFF; 1 – Servo Power ON
5) Velocity Motion Control
Click on the “” or “” button to execute the following procedure:
/* Set velocity mode parameter (value for acceleration and deceleration time)) */
rt = _DMC_01_set_velocity_mode(gDMCCardNo, NodeID, SlotID, Tacc, Tdec);
/* Start velocity mode motion */
rt = _DMC_01_set_velocity(gDMCCardNo, NodeID, SlotID, rpm);
// If value of RPM is greater than 0 then drive motor rotates clockwise. if value is less
than 0 then rotates counterclockwise.
Press the “STOP” button to execute velocity stop or not.
/* Set whether to stop velocity motion control. If stop value is 1 then velocity motion
stops. */
rt = _DMC_01_set_velocity_stop(gDMCCardNo, NodeID, SlotID, stop);
